World of Goo (2D Boy, 1-4 players, Rated E for Everyone—Comic Mischief, 1,500 Wii Points):

World of Goo is an award-winning, physics-based puzzle/construction game made entirely by two guys. Grab living, squirming, talking globs of goo to build structures, bridges, cannonballs, zeppelins and giant tongues. The millions of Goo Balls that live in the beautiful World of Goo are curious to explore—but they don't know that they are in a game, or that they are extremely delicious. World of Goo Corporation is contractually obligated to state that everyone is a winner, and is enthusiastic to celebrate everyone's Goo building opportunities equally.

This game has been getting some fantastic reviews. A shame it's not coming out for WiiWare in Europe - only retail. Looks like I'll have to grab the PC version.

Art Style: CUBELLO (Nintendo, 1 player, Rated E for Everyone, 600 Wii Points):

Art Style: CUBELLO mixes the strategy and feel of a traditional puzzle game with the precision and reflexes required in a shooter. As each stage begins, various colored cubes form into one large object called a Cubello, which floats and rotates as you play. Launch additional cubes from your magazine and try to connect four or more of the same color, removing them from the Cubello and eventually leaving only its core. Take on the challenge of either Stage or Endless mode and watch what happens when Bonus Time is activated. The straightforward controls and goal ensure that anyone can play, while offering enough depth that even advanced players will find themselves quickly addicted to the unique world of Art Style: CUBELLO.

There is a big Virtual Console release as well - SECRET OF MANA is now available for 800 Wii points.
